Frame of my beta65 pro 1s was beaten up pretty bad.
So I thought, I will give it shot for 75mm frame and 40mm props with same 0802 17500kv motors from beta65.

Results were outstanding. More power and flight time.
I get hover throttle between 50 and 60 percentage and get 5 min above flight time.

Motors are directly soldered to FC
Dry weight 28gm.

I am still getting used to go easy on throttle.
